Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: other: EU GHS
Conclusions:
LD50 (rat) > 2000 mg/kg bw
The test substance, when administered by dermal route to rat, under the conditions adopted in this study, did not cause mortality nor toxic effects.
Executive summary:

The acute dermal toxicity of the structural analogue has been determined in a GLP test with rats according to EU methog B.3 in a limit test. The LD50 (24h) value was > 2000 mg/kg bw, the test substance did not cause mortality nor toxic effects under the conditions of the test.

Since EC 700-397-7 is a near analogue to the test substance (EC 413-750-2), the experimental data from this substance were used in a read-across approach.
